Nebula Stereo Delay

What if your delay was as precise as your vision?

Most delay plugins process audio in 32-bit floating point. That's fine — until you stack feedback, filters, and crossfeed into a regenerative loop. Each pass through the feedback network erodes a little more resolution, a little more air, a little more life from your sound. The repeats don't decay — they decompose.

Nebula Stereo Delay runs its entire DSP engine in 64-bit double precision. Every delay line read, every biquad filter, every crossfeed blend, every feedback calculation — all f64, from input to output. The only place f32 exists is the final handoff to your DAW. The result? Repeats that decay gracefully, not digitally. Tail after tail of crystalline echo that keeps its shape through hundreds of feedback cycles.

This isn't a gimmick. It's engineering.
